Abstract

The primary and secondary benefits of tamoxifen as adjuvant therapy in women with hormone-receptor-positive breast cancer are substantial: a 1% decrease in the risk of death each year for 10 years with each additional year of treatment during the first 5 years. Considerable data, however, indicate that these benefits are lost to many patients because of treatment nonadherence. Nonadherence is examined within the framework of the Common-Sense Model of Self-Regulation to describe patients’ models of disease and treatment that organize their thinking and behavior, and the crucial role of the practitioner in addressing and altering these models. Common patient education and social communications about patients’ hormone-receptor-positive breast cancer and tamoxifen treatment promote an acute disease paradigm in which cancer occurs within specific locations and is either present or absent. We recommend that clinicians communicate the concepts of hormone-receptor-positive breast cancer as follows: i. a non-dichotomous systemic disorder entailing a treatment goal of homeostasis and disease quiescence and ii. a disorder undetectable by currently available tests in subclinical states. Equally important, the clinician can provide a comprehensive picture of the well-documented secondary effects of tamoxifen, noting in particular the beneficial effects. Specific action plans, grounded in individual patient understanding, can be developed and reinforced, in an ongoing process that validates and integrates patient values and goals as they change over time.
